Thanks for the pi tip.
I attached the log file and the plist file and I cannot find anything
beside what I sent earlier. It just can't find the backend. And this
happens also exactly the same way, when I don't change to bash with just
running weewxd.

If you go raspi, get a pi4 for the higher performance and memory.
You’ll thank yourself. The 4gb pi4 to me is the sweetspot for weewx.
No need to go pi5.
Your followups re: which mac you use or which shell make no sense to
me if your plist file is correct but you are providing no logs we can
go on, so best of luck I guess. Be sure to set up mac logging per
https://weewx.com/docs/5.1/usersguide/monitoring/ if you haven’t done
so, if you want to keep battling that.

I found more issue. If I run weewxd in zsh, it crashes, hwoever if
I run in bash weewxd works fine. So could it be that I need to
have some way to change the shell to bash in the plist load file,
for the daemon to work? and how would I do this?

Thanks I tried the suggestion using the different python3. It
did not work. I am able to run the whole thing in the virtual
environment, which uses the python3 installed there. So I
guess that might not be the problem. Having now spent three
days on this, I will go out and buy a raspi3 and forget about
the mac. I am convinced it has to do with the imac I am trying
to run this and now the weewx installation. I Installed
everything on my MacBook pro (M1), following the manual and it
run like a charm within half an hour.

I'm guessing that the path used by the dynamic loader is
different when run from a command line, vs run as a daemon.
Did you try the suggestions in the post?

I installed weewx 5.1 for a friend on an iMac
M1. While running just weewxd everything works
great, I get connected andc all the info is
correct in the terminal: (One thing I noted is
that I need to run under bash and not his
default zsh). Thanks for any help, I spent two
days scratching my head and googling.
